The Second Generation Eurocode 9

Abstract

The paper summarizes the main results achieved in the context of CEN Mandate M/515 for amending and extending existing Eurocodes with regard to Eurocode 9 (EC9) on Aluminium Structures (EN1999). The revision process led to introducing additional structural typologies (bridging, roofing and a composite of aluminium–concrete), new connection types, new materials and a new buckling material class and to defining improved buckling curves accordingly. This resulted in the addition of several new annexes to the main text. The new items were mostly planned for Part 1-1, including general upgrading, updating and simplifying, with some new additions where necessary. NDPs were reduced from 89 to 49. A general improvement of editorial aspects was obtained as well.
